Title
Consider a resolution authorizing the Mayor to execute Supplemental Contract No. 1 with AECOM Technical Services for the Brushy Creek Regional Wastewater System East Regional Wastewater Treatment Plant Floodwall Study Project.
Body
The Brushy Creek East Wastewater Treatment Plant is located within the 100-year floodplain limits, endangering wastewater treatment operations during a flood event. The City identified a floodwall as a possible solution to negate floodplain impacts on the plant.
AECOM was contracted to perform hydrologic and hydraulic analysis of the impact a floodwall would have on the floodplain and the surrounding area. This work provided a general idea of the dimensions the floodwall would need to be built to in order to protect the treatment plant. This supplemental would expand on the previous scope to identify vital components needed to move forward with the project and the associated costs. The cost estimate would aid the City in future financial planning.
The City recommends approving the additional scope and fee of $51,270, increasing the total contract amount to $144,910. This cost will be shared by the partner Cities based on their ownership capacities.
Cost: $51,270.00
